Gnom [1K]

To find out the circumference of a circle, you have to multiply the diameter of the circle with pi.(3.14)

First, to get the diameter of a circle you have to multiply the radius by 2.

$10*2=20
$

The diameter is 20 centimeters.

Then, multiply the diameter by pi.(3.14)

$20*3.14=62.8$

The circumference is 62.8 centimeters.

Question in attachment

denis-greek [22]

Answer:

(a) x + y = 63 OR 3x = 63

(b) 21

Step-by-step explanation:

Let Vijay's age be x and Ajay's be y.

Ajay is twice as old as Vijay

==> Ajay's age = 2 × Vijay's age

==> y = 2x

Sum of their ages = 63

==> x + y = 63

Substituting 2x for y:

==> x + 2x = 63

==> 3x = 63

Solving the above-obtained equation:

==> x = 21

Ajay's age = 2 times that of Vijay

==> y = 2x

==> y = 2×21

==> y = 42
